Season, 1 episode 11, 'Hang up': At the start of this episode, since the guys at the station house must go on a call right in the middle of watching an episode of Adam 12, DeSoto and particularly Gage try to inquire about that episode's conclusion. Adam 12 is another show by Emergency's creator, Jack Webb.

By early 1971, battalion chief and certified emergency medical technician Jim Page was assigned the responsibility to coordinate and implement the Los Angeles Countywide Paramedic Rescue Services program. On May 11, 1971, at Fire Station 7 on Sunset Blvd in Hollywood, Jim Page met with producer, Robert Cinadar, who was interested in developing a TV show based on the L.A. Fire Department's emerging Paramedic Rescue Services. When Emergency! premiered in 1971, there were only about a dozen paramedic units across the U.S., but soon after, the show brought recognition of the Paramedic program to viewers in U.S. and ultimately around the world. The realistic rescues on the TV show were widely praised and were used as instructional material by many fire departments, and by 1973, Congress passed the EMS Systems Act which gave financial support for the development and improvement of EMS. Jim Page served as technical consultant and writer of the show, for two years. The character name, John Gage was an homage to Jim Page.
